摘要
通过悬吊转换法在工程实例上的应用,结合模型的建立分析,给建筑在抽柱扩跨方面提供了一种改造思路。运用悬吊转换法加固之后,结构一层、二层、三层的弯矩大幅度减小,能够有效得提高结构的承载能力,裂缝和上部结构的变形都得到了明显的控制,且加固体系传力明确。此外,还介绍了悬吊转换法在施工过程中所需要注意到的重难点,为其他相应工程提供了设计依据。
Through the application of suspension transformation method in engineering examples, combing with the analysis of model building, a transformational idea was provided for the building in the aspect of column extraction and span expansion. After strengthening with suspension transfer method, the bending moment of the first, second and third storeys of the structure were decreased greatly, which can effectively improve the bearing capacity of the structure. The cracks and the deformation of the upper structure were obviously controlled, and the transmission force of the reinforcement system was clear. In addition, the important and difficult points to be noticed in the construction process of the suspension conversion method were also introduced, which provides design basis for other corresponding projects.
